Keith Roy began warning his clients about a faltering Vancouver housing market in early 2012. The realtor says he was tipped off not by industry statistics, but by chatter across backyard fences. “When you hear about a homeowner who thinks his neighbour got too much money when he sold his house, you know there’s something going on,” says Roy. “That was the first clue.”

The next shoe to drop was a handful of homes in desirable west side neighbourhoods that took a few extra days to sell. Sensing a shift in the market, Roy put his own house up for sale in June and penned a blog posting the following month that advised people to “cash out.” Though he was criticized by fellow agents for breaking rank, Roy says he now feels vindicated after watching Vancouver home sales crumble to their lowest point in more than decade, with prices falling 3.5 per cent since hitting a high last May. The lesson? Recognizing a looming real estate downturn is more art than science; once it shows up in the numbers, it’s too late to do much about it. “One day the phone just stops ringing,” Roy says. “Then you’re in it.”

It’s not just Vancouver where realtors’ BlackBerrys no longer buzz. In Toronto, the city’s once insatiable demand for living in 650 sq.-ft. glass boxes has evaporated overnight. Condo sales are down by 30 per cent, while prices have fallen by 4.5 per cent. Some proposed projects have been put on hold, while some angry investors—like those who bought luxury suites at the Trump International hotel—are desperate to get their money out, and have turned to the courts. Even the Bank of Canada, which has helped inflate the bubble by tempting Canadians with years of rock-bottom interest rates, has issued a rare warning about the risks posed to the broader housing market of too many condo developers in cities like Toronto and Vancouver chasing too few buyers.

A housing correction—or, possibly, a crash—is no longer coming. It’s here. And you don’t have to own a tiny $500,000 condo in downtown Toronto or a $1.3-million bungalow in Vancouver to get hurt. With few exceptions, the impact will be indiscriminate as the euphoria of rising house prices is replaced by fear. The only question now is how bad things will get. If the decline picks up speed, as many believe it will, there could be a nasty snowball effect. Construction jobs will be lost. Homeowners will end up underwater. Consumers may stop spending. “I’m getting very nervous,” says David Madani, an economist at Capital Economics, who has been predicting a drop in housing prices of up to 25 per cent in Canada. “I know I’m a bear, but the housing market itself has the potential to put us in a recession, let alone what’s happening in Europe and the U.S.”

Ray Charles couldve saw this coming. When the US was deep in its own housing correction, Vancouver bucked the trend, but the main issue was income-to-housing ratio was still totally out of whack. I think i even read somewhere that Vancouver was more out of whack than Manhattan. If you didn't cash out, you were a moron.
